The SPListEventReceiver class is not instantiated, but the list event receiver class of a custom event handler must derive from this class and override its methods for the event types that are handled.

Like other events, list events come in both Before synchronous and After asynchronous variants. List events are not generally raised as the result of a bulk operation. For example, creating a new Microsoft SharePoint Foundation list inherently creates a set of fields, but FieldAdding events are not raised.
